MOBILE HOME INSTALLATION
Modern mobile homes have been designed and built to be energy efficient. 
Install smoke alarms as recommended above. In older mobile homes that are 
not well insulated compared to present standards, extreme heat or cold can 
be transferred from the outside to the inside through poorly insulated walls 
and roof. This may create a thermal barrier which can prevent the smoke from 
reaching an alarm mounted on the ceiling. In such units, install the smoke alarm 
on an inside wall with the top edge of the alarm a minimum of 4” (10 cm) and 
a maximum of 12” (30.5 cm) below the ceiling.
If you are not sure about the insulation in your mobile home, or if you notice 
that the outer walls and ceiling are either hot or cold compared to the room 
air temperature,  install the alarm on an inside wall.  NFPA 72 (National Fire 
Protection Association) requires smoke alarms be installed in each sleeping area.
 WARNING: Test your smoke/CO alarm operation after mobile 
home has been in storage or unoccupied and at least once a week 
during use.
